Map view layer: Avalanche observations

REQUIREMENTS
Permission	All users
Connectivity	Online only

This document describes the functionality of the Avalanche Layers layer of the Map view of the InfoEx report.

The goal of the Avalanche Layers map layer is to provide users with a spatial overview of all the avalanche observations submitted to the InfoEx in the time period of the current report and give quick access to the individual avalanche records.

ISSUE

Avalanche observation associated with multiple locations are currently missing in the avalanche layers. JIRA: -1236 (Dec.20,2013)

Layout

Fig. 1: Avalanche layers of map view of InfoEx report.

Fig. 2: Avalanche observation pop-up balloon.

The avalanche layers map layer shows the point locations of all the avalanche observations included in the current report (Fig. 1).

Avalanches are shown at the following locations:

• Avalanche observations that were only associate with a preexisting location from the location catalog are shown at the centre point of this location.
• Avalanche observation that have been given a precise map location (click here for more information on how to 'drop a pin' for an avalanche observation) are shown exactly at this location.

NOTE	Avalanche observations with a precise location are marked with a next to the location name in the observation pop-up balloon (see below for more details)

The color and size of the avalanche icons represent typical avalanche size:

• Yellow: Size 1.0 and 1.5
• Orange: Size 2.0 and 2.5
• Red: Size 3.0 and larger

The icons of the avalanche observation have an additional label indicating the trigger type.

The main trigger types are listed under the Avalanche Layers label in the layer hierarchy panel left of the map (Fig. 1):

• Natural
• Skier
• Snowmobile
• Over-snow vehicle
• Helicopter
• Explosives

Functionality

• Click on a main trigger type in the layer hierarchy panel to directly zoom the map to the area that has avalanche observations of the particular trigger type.
• Click on the check box next to the main trigger types in the layer hierarchy panel to show/hide the avalanche observations of the particular trigger type.
• Click on the icon of an individual avalanche observation to view its complete record in a pop-up balloon (Fig. 2). The pop-up balloon contains all of the information that was submitted for the observation including links to any associated attachments.
